Isoflurane is used for the induction and maintenance of general anesthesia during surgical procedures, including major surgeries, cesarean sections, and outpatient operations. It is suitable for patients of various ages requiring general anesthesia.
Isoflurane works by depressing the central nervous system, primarily enhancing inhibitory neurotransmission and reducing excitatory signaling in the brain. This produces loss of consciousness, analgesia, amnesia, and muscle relaxation necessary for surgery.
Isoflurane should only be administered by trained anesthesia providers in settings equipped for airway management and monitoring. It may cause respiratory depression, hypotension, and malignant hyperthermia in susceptible individuals. It crosses the placenta and should be used cautiously in pregnancy.
